The course concerns the structure and transformation of global cities linked to six specific countries over four continents. The course will be characterized by its rigorousness, creativity, and sensitivity in making visible both social inequalities and the social groups affected by them, in particular those hard-to-reach groups who are not considered in statistical and macro-sociological analysis. By focusing the course on social inequalities and subcultures in New York City, the course intends to generate a vast sociological body of work that will deepen our understanding of the transformation of contemporary societies from glocal and intersectional perspectives. The course explores realms of Sociology, Anthropology, Philosophy, governance, Economics, Geo-Politics and culture and to provide imaginal descriptions and representations in the creation of new knowledge designed to offer the widest facilities for significant conversation. The other cities, Tokyo, Nairobi, Manila, Mexico City, Paris, what has been called the “urban bottoms” will also be examined.
